AbstractChart quadrat maps offer a unique source of data on long-term trends in grasslands. Through the use of film-scanning computer systems, this information can be more easily processed and used in plant demographic studies. There is a large and varied assemblage of data that has been collected over the years on the semiarid grasslands information that can be valuable in studying today's important natural resource management problems. To a large extent, however, much of this information has not been sufficiently utilized because of the time involved in the effort. One such source of data of this type is that available from chart quadrat mappings. This paper presents a method which enables one to more easily quantify and use the information on chart quadrat maps and some examples of how these data can be used in plant demographic work.
